WANTED: Big and tall guys to take off their clothes – and donate them.Career Gear needs them. For the last two years, the nonprofit group has been giving unemployed men suits, shirts, ties and shoes – and the self-esteem that goes with them – to help them find jobs.

But for every three or four men who leave 11 Penn Plaza with a fresh suit of clothes, says Gary Field, Career Gear’s founder and executive director, at least one man can’t be fitted, for one reason or another.

“A man came in the other week who used to be a stock trader from Eastern Europe, and he was walking around the city in sandals and socks,” Field recalls. “He’s a political refugee and he needed a pair of shoes, size 13. I had nothing.

“Another guy came in who was 6-[foot]-3. We were able to find him jackets that fit in the shoulders, but everything was too short in the arms . . .

“Our mission is to make men feel good about themselves,” adds Field, “but when they come here and we have nothing to fit them, well, that defeats our purpose.”

Field knows how these men feel. About a dozen years ago, he says, he came to New York from Toledo, Ohio, without a college degree or a clue, and fell into a series of dead-end jobs, drugs and alcohol.

After he sobered up, he entered a job-readiness program and scraped together $50 to buy a suit in a thrift shop for his first interview. Field landed the job – and eventually earned a master’s degree in social work – but he never forgot that first suit.

Inspired by the Dress for Success program for jobless women, Field and his partner, costume designer David Wollard, started Career Gear in 1998. They’ve since suited 1,000 men, most of them referred to by job-training programs around the city and in Miami, Cleveland and Washington, where Career Gear recently set up branches.

Some men, like the political refugee Field sought shoes for, are recent immigrants who don’t own a tie; others are men who’ve just gotten out of rehab or jail. All are eager to find work – whether it’s repairing Xerox machines or selling hardware – but don’t have the clothes to get the job.

“If it weren’t for Gary, these men wouldn’t be prepared for an interview,” says Deborah Freeland of the New York Association for New Americans, a job-placement agency.

“When these guys put on those suits, they see themselves in a new light. And when you feel good, you interview good.”

These days, there are lots of suits in Career Gear’s basement headquarters, but racks for sizes 46 and up hang empty.

Also in short supply are winter coats, shirts with neck size 17 and up, and shoes – preferably new ones – size 10 and up.

“Casual Male Big and Tall came through with $10,000 worth of clothing recently,” Field says, “but we ran through it in five weeks.”
